Hi! i noticed my Note 3 has a red / purple line on the bottom of the screen,i see it when access *#0*# menu. Is like a red/purple very thin shadow, seen on White background. Is a AMOLED "feature" ? You have that on your Note 3?

Yes, I have that. As far as I know, that's perfectly ordinary when you're having a LED display showing a white screen..

mine doesn't have anything like that, very uniform white, top to bottom. Could the screen be miss aligned and the very last row of green subpixels too low to be visible to offset red blue and therefore giving red/purple hue? But since it's on the very bottom I wouldn't worry about it too much even if I had it.

It is because the PenTile technology.
There are 2 green subpixels, but just 1 blue and 1 red subpixel for each pixel. i have that line too, but its more like purple for me

I can notice it too, but only if I'm looking for it. It's not an issue in day to day usage.

The diamond PenTile matrix is responsable for some chromatic aberation. As said ReNeH99, the two green subpixels are to blame. For example, if you look very carefully at the top of the display on white wallpaper, you see the first row of pixels are fade in green/blue shadow, but less vissible then the lower red/purple fade.
I attached the pen tile matrix used in Note 3 display.

I see it at the bottom of my screen just above the home button. It's hardly noticeable though.
